FIELD: construction.
SUBSTANCE: invention can be used in production of building materials. The method for manufacturing raw materials for producing technogenic anhydrite binder includes mixing calcite with sulfuric acid. Sulfuric acid with a concentration of at least 50% by weight is heated to a temperature of 100-320°C and mixed with calcite crushed to a particle size of 0.5 mcm to 55 mcm, maintaining the process temperature in the above range, until a granular material is formed, while the ratio of the weight fractions of sulfuric acid and calcite is 1:(1.3-1.5).
EFFECT: increase of the shelf life of raw materials, which makes it possible to produce a high-strength binder.
